Rotary display stands

Abstract

A display stand for a radial group of data units rotatable by a central spindle journaled in the base of the stand. The inner portions of the units occur between facing cup-shaped guides carried by the spindle; and the units and walls of the cups have interlocking formations allowing units to be coupled with or disengaged from the guides. However, the units are retained for rotary and selective handling when coupled with the guides.

I claim: 
     
       1. A display stand for a plurality of radially mounted planar data displaying means comprising a base element having a flat bottom of a length greater than the length of the planar data means and a base width at least sufficient to provide stability with a wall at each end of said bottom perpendicular thereto and an opening in the distal end of each of said walls; a spindle inserted in said openings, said spindle comprising a mid-portion and two end portions, the mid-portion of said spindle being of a greater diameter than the end portions to provide a shoulder at each end of said mid-portion, means on at least one end portion to cooperate with spindle knobs to secure said spindle within said base; means to support said data display elements on said spindle comprising a pair of cup-shaped elements each having an opening in the bottom surface to frictionally receive the end portion of said spindle and an external and internal bead on the rim of each element, each element being inserted on the end portion of said spindle in frictional engagement therewith and with said shoulder, the elements further being in facing relationship with reference to said beads; each of said data display elements comprising an envelope-like element of flexible material having an opening for the insertion and retension of the data, and a portion for slidable assembly on said cup elements, the portion of the envelope-like element to be assembled on said cup elements having a pair of spaced circular openings and a diverging slot parallel to said spindle and leading from each opening to the adjacent outer edge of said envelope-like element, said openings being of a size to receive said beads on each of said cup elements in slidable relationship therewith, said slot at its intersection with its opening being of a width to receive the wall of said cup-like element and to form at least one stop so as to retain said beads within said openings. 
     
     
       2. A display unit according to claim 1, wherein said base element is of a U-shaped configuration lying on one of the upstanding walls as said base.
